Sort of funny how heavy a barrel gets when it exceeds the diameter of the flash hider in front of the gas block and is even thicker behind it!

I asked HK if the production MR556's were going to have the 416N/IAR contour or if they were going to have the boat anchor contour. They were less than amused. No way in hell I'd buy an MR556 with an extra 1lb on the front end, that's just a ridiculous amount of weight where it isn't needed.
